Air bed

ABSTRACT

An air bed comprises a mattress which is inflatable and collapsible and a lot of supporting pieces provided therein. The supporting pieces are spaced equidistantly and arranged in a plurality of transverse and longitudinal lines. The upper and the lower ends of the supporting pieces are combined respectively with the upper and the lower sides of the mattress. The mattress is provided with a valve for aerating and discharging air. Combining the supporting pieces with the mattress can save material and reduce cost of production, and the air bed after aeration can give appropriate elasticity for comfortable feeling of a person lying thereon.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to an air bed, and especially to an air bed composed of a mattress and a lot of supporting pieces able of saving material and reducing cost of production, and after aeration, the air bed can give appropriate elasticity for comfortable feeling of a person lying thereon.

2. Description of the Prior Art

Sleeping is necessary for a man, and using a mattress can make a person lying on the mattress for more comfortable sleeping. Mostly a normal mattress is fixedly placed on a rack. When we go outside for camping, or some visitors come to our houses and stay overnight; if beds available are inadequate, air beds can suitably give their useful function.

As shown in FIG. 1 showing the structure of a conventional air bed 1, the structure comprises an unventilated but inflatable and collapsible mattress 2 and a plurality of elongate supporting strips 3 provided in the mattress 2. The supporting strips 3 have upper and lower surfaces 5, 6 combined with the upper and the lower surfaces 7, 8 of the mattress 2 in an undulated line contacting mode, so that after aeration, the mattress 2 is inflated for supporting weights of persons; however, the above structure uses more material, it needs to be improved in consideration of saving energy source as well as cost of production.

In view of this, and in order to get rid of the above defects to make an air bed not only able to effectively save material in use, but also able to reduce cost of production, the inventor provides the present invention based on his professional experience of years and continuous study, developing and improvement.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide an air bed which effectively saves material and reduces cost of production by providing improved supporting pieces, and after aeration, the air bed can give appropriate elasticity for a person to lie thereon.

To get the above stated object, the air bed provided by the present invention comprises: a mattress with a flat and elongate body which is inflatable and collapsible and is provided with a valve for aerating and discharging air; a lot of supporting pieces installed inside the said mattress and arranged in a plurality of lines, the supporting pieces are combined with the upper and the lower ends with the upper and the lower sides respectively of the mattress. Whereby combining the said supporting pieces with the said mattress and aerating, the surfaces around the said upper and the said lower sides of the said supporting pieces are fully inflated that give appropriate elasticity for feeling comfortable of a person lying thereon.

The present invention will be apparent after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 2 and 3 showing a preferred embodiment of an air bed 10 of the present invention, wherein the air bed 10 comprises a mattress 20 and a lot of supporting pieces.

The mattress 20 with a flat and elongate body is inflatable and collapsible, and combined from six unventilated sheets. The upper sheet 21 is fixedly provided near a corner thereof with a ventilation valve 22, thereby air can get into the elongate body to inflate the latter by aeration and when in discharging air, the mattress 20 can be collapsed to save the space of storing.

The supporting piece 30 is installed inside of the mattress 20. Each supporting piece 30 has an upper end 31 and a lower end 32 of equal lengths. The middle portion thereof is narrower to form recessed areas. Every two supporting pieces 30 has therebetween transversely a distance “b”, and longitudinally a distance “c”, so that all the supporting pieces 30 are arranged to form an array.

Referring to FIGS. 4 and 4 a, in a high-frequency irradiation mode, each supporting piece 30 has its upper end 31 stuck integrally on the upper side 21 of the mattress 20 in a plurality of lines, and has its lower end 32 stuck integrally on the lower side 23 of the mattress 20 likewise. When the mattress 20 is aerated, and by connecting of the mattress 20 with the supporting pieces 30, the surfaces of the upper and the lower sides 21, 23 of the mattress 20 form an air chamber 40 surrounding the combination spots of them with the supporting pieces 30, this can give appropriate elasticity for supporting the weights of persons lying thereon.

The present invention is advantageous in that: the plural supporting pieces in the air bed are arranged to form an array, each supporting piece is an individual piece, they are economized in using material; and by combining of the upper ends and the lower ends of them with the upper side and the lower side of the mattress, after aeration, the surfaces of the upper and the lower sides of the mattress are fully inflated at the areas around the combination spots of them with the supporting pieces, this can give appropriate elasticity for comfortable feeling of a person lying thereon.

In conclusion, and according to the content disclosed hereinabove, the present invention surely can get its object to provide an air bed effective in saving material and cost of production. Having thus described my invention with the value of practicality, what I claim as new and desire to be secured by Letters Patent of the United States are: 

1. An air bed comprising: a mattress with a flat and elongate body which is inflatable and collapsible and is provided with a valve for aerating and discharging air; a lot of supporting pieces installed inside the said mattress and arranged in an array with a plurality of transverse and longitudinal lines, said supporting pieces in each of said lines are spaced equidistantly, the upper and the lower ends of each of said supporting pieces are of equal length and are respectively combined with the upper and the lower sides of the said mattress, the middle portion of the said supporting pieces is recessed inwardly; whereby combining the said supporting pieces with the said mattress and aerating, the surfaces around the said upper and the said lower sides of the said supporting pieces are so fully inflated that give appropriate elasticity for a person lying on the said air bed.
 2. The air bed according to the claim 1, wherein the upper and the lower ends of the said supporting pieces are combined respectively with the upper and the lower sides of the said mattress by a high frequency irradiation.
 3. The air bed according to the claim 1, wherein the number of the said supporting pieces in each said longitudinal lines are equal and the said transverse lines are mutually parallel too.
